I've successfully set up GlusterFS 3.0 with a single server. I brought on a 2nd server and setup AFR and have been working through the mirroring process. I started an "ls -alR" to trigger a complete mirror of all files between the two servers. After running for about 16 hours I started getting kernel out of memory errors. Looking at top I see: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2561 root 15 0 13.0g 8.9g 860 S 7 91.6 60:56.02 glusterfs Seems that the client has used up all my memory (RAM and SWAP). Killing the process returned all the memory to the OS. BTW - I'm working on a 2.3Tb store that contains about 2.5 million files in 65K folders. Thoughts? Larry Bates vitalEsafe, Inc.
